我在eclipse内部使用Tomcat 8的本地实例开发了一个Spring Messaging应用程序。这在eclipse内部工作得非常好，但是当我创建一个war并将其部署在Tomcat的webapps目录中时，它不起作用。这些是我到目前为止所做的步骤。我在windows机器上使用gradle构建系统。因此我运行了gradlew build。这在root/build/lib中生成了一个war文件，我转到本地tomcat的bin目录并运行start. bat这设置Tomcat运行，然后我将war复制到tomcat的webapps目录。我得到的只是一个404。

这是我的catalina. log

我有几个问题，

1. 我如何部署战争并让它在Tomcat中运行。
2. 当我在eclipse中运行时，我没有看到在build/lib中实际创建了任何战争，那么eclipse是如何使用Tomcat运行我的webapp的呢？
